A solution of sulfuric acid at 60°F is found to have a sp gr of 1.22. From the tables inPerry's Chemical Engineer's Handbook, the solution is found to be 30 percent byweight H2SO4. What is the concentration of H2SO4 in the following units:
(a) lbmol/gal,
(b) lb/ft3, (c) g/L,
(d) lb H2SO4/lb H2O, and
(e) lb mol H2O/lb mol totalsolution?
what is the maximum profit obtainable per pound of chemical Z ?
200 kg of carbon dioxide are stored in a tank at 25 °C and 70 bar. Is carbon dioxide an ideal gas under the conditions in the tank?
Main objectives of the computer aided modeling and simulation system - Critically analyze the applicability, domain, features and advantages of the various systems available.
Outline the provisions of Occupational Safety and Health Act 2005 with regard to Substances hazardous to health Describe four types of hazard which arise from the use of chemicals
Chemical X costs $0.09 per pound. Chemical Y costs $0.04 per pound. Chemical Z sells for $0.80 per pound. If one-half of the selling price for chemical Z is due to costs other than for raw materials, what is the maximum profit obtainable per pound..
A sealed rigid tank contains 1 kg of wet steam at 300 °C. The fraction of the liquid in the tank is not known. Upon adding heat to the tank it is observed that the vapor condenses. The heating stops when the system becomes saturated liquid. At tha..
The vessel is 4 m internal diameter and 20 m long. Estimate the minimum wall thickness required to resist this pressure, for the cylindrical section and the heads. Take the design pressure as 12 bar and the maximum allowable stress for the materia..
Acetylene is formed as a by-product in the manufacture of ethylene. It is removed by selective hydrogenation using noble metal catalysts (see, for example, US 7,453,017). A particular catalyst achieves 90% acetylene saturation with 50% hydrogen se..
A larger distillation tower is needed for the same mixture, and it has been decided to use a 12-in. inside-diameter tower with the same type and size of packing.
Develop a mathematical model that describes how the pressure in the tank varies with time.
To be satisfactory quality the ratio of 'A' to 'B' in the mixture must be 100 to 1or higher. 'D' reacts with both 'A' and 'B' as follows;A + D?R-rA= 21 CACDB + D?S-rB= 147 CBCDAssuming that the reaction go to completion, how much 'D' need be added..
